Those are not the dump files, you can find the dump files at [1]. We create those dump files on monthly basis, and the users can use the latest one as the starting point of synchronization. The files under [2] are the changeset files, i.e. the diff files resulting from comparing the newly extracted triples with the existing ones. Those files are the ones used for synchronization. The sync tool [3], we have developed, continuously downloads those changeset files and use them to synchronize a DBpedia-Live mirror with the official live endpoint. > > Also for inserting data , if I will directly import this dump to > repository than it will create duplicate records rather than updating > records.I am under such impression that there is no function available > for bulk update/delete using the live update dump. > > Hence I am thinking to follow below approach. > > "Process the DBpedia update live dump line by line and insert/delete > it into/from database using INSERT DATA or DELETE DATA queries." The sync tool mainly works with Virtuoso [4], but since it's open source you can easily adapt it to work with Sesame if necessary. You can find more information about DBpedia-Live at [5]. > > > Please correct me if I am wrong. > > -- > Regards > Gaurav Pant > +91-7709196607,+91-9405757794 [1] http://live.dbpedia.org/dumps/ [2] http://live.dbpedia.org/liveupdates [3] http://sourceforge.net/projects/dbpintegrator/files/ [4] http://virtuoso.openlinksw.com/ [5] http://wiki.dbpedia.org/DBpediaLive -- Kind Regards Mohamed Morsey Department of Computer Science University of Leipzig ------------------------------------------------------------------------------ Everyone hates slow websites.
